Check if device supports LTE Data Connection

Question

I am learning Android development to my own and wandering to know if my device has the hardware that can support the LTE network.

I am trying the below, but I think it is giving me wrong data

ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
   NetworkInfo[] info = cm.getAllNetworkInfo();
   for(int i=0; i <info.length; i++){
       Log.i("netinfo"+i, info[i].getType()+"");
       Log.i("netinfo"+i, info[i].getTypeName());
       Log.i("netinfo"+i, info[i].getSubtype()+"");
       Log.i("netinfo"+i, info[i].getSubtypeName());

So in short I just want to know if my device supports LTE data network or only 3g or 4g networks.

Thanks in Advance

Answer 1

I'd go with:

int TelephonyManager.getDataNetworkType()

compare the value with the (defined) constants:

NETWORK_TYPE_UNKNOWN, NETWORK_TYPE_GPRS, NETWORK_TYPE_EDGE,  
NETWORK_TYPE_UMTS, NETWORK_TYPE_CDMA, NETWORK_TYPE_EVDO_0,  
NETWORK_TYPE_EVDO_A, NETWORK_TYPE_1xRTT, NETWORK_TYPE_HSDPA,  
NETWORK_TYPE_HSUPA, NETWORK_TYPE_HSPA, NETWORK_TYPE_IDEN,  
NETWORK_TYPE_EVDO_B, NETWORK_TYPE_LTE, NETWORK_TYPE_EHRPD,  
NETWORK_TYPE_HSPAP, NETWORK_TYPE_GSM, NETWORK_TYPE_TD_SCDMA,  
NETWORK_TYPE_IWLAN, or NETWORK_TYPE_NR  

NETWORK_TYPE_GSM is 2G

NETWORK_TYPE_GPRS, NETWORK_TYPE_EDGE is 2,5G

NETWORK_TYPE_UMTS is 3G

NETWORK_TYPE_HSDPA, NETWORK_TYPE_HSUPA, NETWORK_TYPE_HSPA, NETWORK_TYPE_HSPAP are 3,5G

NETWORK_TYPE_LTE is 4G

NETWORK_TYPE_NR is 5G

This is the API reference
